Benefits of Laminated Safety Glass

A typical laminate makeup is a 3mm glass / 0.38mm interlayer / 3mm glass. This gives a final product referred to as 6.38mm laminated glass. Multiple layers of vinyl and thicker glass increase the strength of the finished product.

SAFETY

Laminated glass is designed to minimise serious injury to humans that may accidentally collide with glass. The virtually inseparable thermochemical bond between the PVB interlayer and glass causes the glass to adhere to the PVB interlayer, holding the glass sheets together.

SANS 1263 Part 1 requires that a lead-filled bag weighing 45kg is dropped through a pendulum arc from a height of 450mm and strikes the centre of the test glass with an impact force of 203 Joule. In order to comply with the safety glass regulations, the glass should break safely. In the case of laminated glass, the impact of the swing bag should not rupture the interlayer to allow a 75mm sphere to pass through the laminated glass.

The practicality of this test is that should a human collide with the glass, the injury will be minimised.

SECURITY

For glass applications that require greater resistance to forced attack than what normal strength laminated safety glass offers, increasing the thickness of the PVB interlayers provides additional protection to people and assets.
